    The thin ones are often for slitting, for broach bushings you use like I think 1/4 , 5/16, and 3/8 sort of sizes. Often staggered tooth cutters.

      A direct simple answer to original question. 1/2" and 5/8" B bushing and 1/8" B broach. The broach will come with appropriate shims. Can get offshore broaches from ebay for around $40. I think KBC and probably all the other tool places have them too.

        I recently purchased a 6mm C broach on the bay. It was Chinese. I was cutting a 32mm thick hub of 1045 steel. I broke 2 teeth off the broach on the first cut. Buying Chinese always carries a risk. Spend a little more and order DuMont.

          I picked up two sets for under $50 dollar each. All Standard thick and thin.. The big set was from the tent sell at Grizzly tools, the other is auction.
